Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Compile ffmpeg with x264 shows : ERROR : libx264 not found
6 mai 2019, par NKamTrying to install ffmpeg from source with libx264 package. When I compile ffmpeg can’t find x264 because it is not installed.
I followed ffmpeg installation guide.I tried to install and compile ffmpeg locally and found out in folder ffmpeg_build/include I don’t have x264 files installed.
To compile libx264 I used :
cd /ffmpeg_sources &&
git -C x264 pull 2> /dev/null || git clone —depth 1 https://code.videolan.org/videolan/x264.git &&
cd x264 &&
PATH="$HOME/bin :$PATH"
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure —prefix="$HOME/ffmpeg_build" —bindir="$HOME/bin" —enable-static —enable-pic &&
PATH="$HOME/bin :$PATH" make &&
make install
I changed url to https://code.videolan.org/videolan/x264.git, because this url https://git.videolan.org/git/x264 from guide not working
Here how config.log’s last lines look like
test_cflags -Wmaybe-uninitialized
test_cc -Wmaybe-uninitialized
BEGIN /tmp/ffconf.1LD1vklR/test.c
1 int x;
END /tmp/ffconf.1LD1vklR/test.c

I want ffmpeg to find x264, if it is not installed how can I find way to install.

compiling ffmpeg with decklink fails on debian
16 avril 2019, par derhottevomdorfFollowing FFmpeg Wiki : Ubuntu. All dependencies, gcc, nasm, etc. should be up to date. I compiled
ffmpegsuccessfully without Decklink library.Now adding
--enable-decklinkand the required includes from Decklink SDK I get the errors below.Any ideas ?
